IMPROVEMENT IN LANTERNS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, ANTHONY M. DUBURN, of Chicago, in the county of Cook, and State of Illinois, have invented a certain new and useful Improvement in Lanterns and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the drawingshereunto annexed, and formingpart of this petition. V

In order to show the mode of. constructing my invention, I will now proceed to a description thereof.

Figure 1 represents the ring, attached to the base of the guards, and is the main feature of my invention.

Letter A represents a narrow strip of sheet metal, formed in a machine, in the shape shown and described,

'viz, the parts at A, between the corrugations or loops 0 c c c c c, is of'asemicircular form, convex side outward so as to partly enclose awir'e ring, represented by the red line in fig. 1, the dark portion representing the sheetmetal rim, the wire being used as a stifl'ening only. 2

Letters '0 represent the corrugations or loops, formed as receptacles for. the ends of the upright guards, (one shown, Figure 5,) and of a sufiicient depth to allow the insertion of the end of the said upright guard, without forcing the wire ring out of place. The end of the metal rim is riveted or locked in such a way that it will not'come apart when dipped in the melted metal mentioned below.

To manufacture, the metal rim is cut the length and width desired, then passed through a suitable machine and formed in the shape shown and described. The ends are then fastened, and a wire ring;(red line in fig. 1) is then sprung into the hollow of the metal rim, said wire ring being partly enclosed thereby. This combined rim is then put on a suitable frame, and the ends of the upright guards (fig. 5) are thcti inserted, one guard in each loop or corrugation. The middle ring or rings-m are then put on and wired in the usual manner. The entire guard is then removed from the frame and dipped in a bath of melted tin or solder, which firmly fastens each joint, making an unusually strong and durable guard. The top, L, is then attached in the usual manner. The globe E is then inserted in the base, F. The guard G is then passed over and enclosing said globe E, and is seated on the flange at H H, to whichit is secured, either by springs, hinges, or otherwise, as may be desired.

1 do not claim broadly an adjustable guard-lantern; neither do I claim broadly a sheet-metal rim; but

What I do claim, and desire to secure by Letters Patent, is-

1. The sheet-metal rim A, when formed in the shape shown and described, and for the purpose herein set forth.

2. The wire ring B, when used as a stifl'ening, in combination with the sheet-me tal rim A and corrugations orloopsccc'ecc. I

In testimony that I claim the foregoing improvements, I have hereunto set my hand, this,-the day of .February, 1868.
